In our experiments, we use three different speech corpora which are described in Table REF . We downsample speech files at sampling rate of 16 kHz when required. The EmoDB is a German language corpora while RAVDESS and IEMOCAP are in English. For IEMOCAP database, we select only four emotions (Angry, Happy, Sad and Neutral) as some of the emotion class have inadequate data for training neural network models [1]}. We perform cross-corpora SER experiments by selecting the same four emotions.
